Abstract

Nouveau détecteur optique de fumées basé sur la diffusion d'une source lumineuse ponctuelle dont la variation de diffusion est perçue par un phototransistor orienté, spécifiquement sensible. Suivant la figure 1, le détecteur est caractérisé par : - deux sources lumineuses à impulsions ponctuelles placées dans une chambre noire dotée de chicanes - un phototransistor de réception orientée destiné à recevoir la lumière diffusée, - un circuit électronique vélocimétrique de détection, - un circuit électronique distinguant l'alarme d'un phénomène de dérangement.
